delete_playlists

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=true. The description adds no extra behavioral context such as whether playlist items are deleted, whether the deletion is permanent, or any authorization requirements. It adds no value beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely terse with a clear Args section. Every sentence is functional, but the lack of substance is not compensated by structural elegance. It is concise in length at the expense of completeness, so it earns a 4 rather than a 5.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

This is a destructive operation but the description lacks any contextual details like cascade behavior, authorization, or the distinction from the path-based sibling. It also does not describe any output or error conditions, leaving an agent with ambiguous guidance for a potentially destructive call.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has zero description coverage for rating_key, so the description's line 'The rating key of the playlist to delete' is the only clarification. It correctly identifies the parameter's meaning but does not explain why it is optional, how to obtain it, or whether it is required for a successful delete.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the operation explicitly ('Delete Playlist') with the resource and the rating_key argument. However, it does not differentiate from the sibling delete_playlists_by_playlist_id, which likely performs a nearly identical action, so it misses the distinction that would earn a 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no guidance on when to use this tool versus the sibling delete_playlists_by_playlist_id, nor any prerequisites or side conditions. The only clue is the named parameter, but no alternative or exclusions are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
